Heat Retention Cooking (or Making Applesauce in Honduras)

For most of us who read blogs like this we don't put a lot of thought into how we cook.  That's because we're using a gas or electric stove, but what if you didn't have one of these modern conveniences?

Well, that's the very real situation for about 3 billion people, or about half the world's population!
This stove has a chimney and yet still produces a lot of smoke in the room.
Burning with wood, or other woody materials, brings up several issues.  The first is obviously the time spent gathering and cutting the wood.  While this can represent upwards of three to five hours of work per day it still doesn't rank in the major problems.
This stove has no chimney has turned the walls and ceiling black.
One of the biggest problems cooking with wood is the smoke produced.  Indoor air pollution from cook fires poses a serious health problem with twice the incidence of Acute Respiratory Infection or ARI.  The World Health Organization reported in "Acute Respiratory Infections" Update September 2009, that "Acute respiratory infections (ARIs) continue to be the leading cause of acute illnesses worldwide and remain the most important cause of infant and young children mortality, accounting for about two million deaths each year..."  ARI is not the only health issue as the smoke also causes eye problems and the open fires are often the source of burns for children and adults alike.

There are many solutions to remediate this crisis in the kitchen and one of them may be "Heat Retention Cooking," or HRC!  HRC is a simple process of boiling foods without meat for about 10 minutes, or with meat for about 15 minutes, and then insulating the pot to let the cooking continue for three to five hours.  When the pot is taken out it's still piping hot and the food is ready to serve!

We have had success making chicken and rice, cooking beats, and in the clip below Ellen demonstrates how to make applesauce!


We have been able to demonstrate this cooking to three families so far and one of them is now experimenting at his own house to devise was to insulate the pot.  He actually filled a metal tub with wood ash and then set the hot pot in the ash so that the ash almost reached the lip.  The top was covered with a cloth.  His wife was cooking rice and they said it came out perfectly!

We're working on trials of making an insulated box out of layers of cardboard glued together.  While this should work there are some logistical considerations such as: how will the folks get all the cardboard needed to build the box?  Even so, we are moving forward and praying for the Lord to provide the needed guidance!

  1. I like your heat retention video! Can you give an estimate for how much fuel is being cut down by using a combo of a fuel efficient stove and then heat retention for cooking? Would that cut the wood required down to a 1/10, or perhaps more?

    1. The fuel savings can really vary greatly. Where heat retention cooking comes in as a champ are those things that have to cook longer on the stove top.

      When we showed the folks in Tutule the beets they immediately saw the value because beets would normally cook for 45 minutes on the stove.

      Frijoles (beans) can have to cook from 2 hours, for fresh beans, to 3 and even 4 hours, for older dry beans. So, to bring them to boil for just 10 minutes and then set them off to the side for the remainder of the cooking is huge.

      With an example like that you're not even using a tenth of the fuel and that's even if you're not using a fuel efficient stove. So, this is simple technology that can greatly impact their daily lives.
